Description

Technical Field

[0001] The utility model relates to the technical field of mask production, in particular to a mask nose bridge line welding machine. Background Art

[0002] A mask is a sanitary product, generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to prevent harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent or when working in a dusty environment, wearing a mask is very effective.

[0003] The existing cup-shaped masks not only conform to the shape of the human face contour, but also have a nose clip with a fixed angle on the upper part of the mask. After the user puts on the mask, he presses the nose clip hard to fit it on the bridge of the nose, so that the mask fits tightly to the face. In the current mask production process, the external bridge of the nose line is generally fed and welded by manual feeding or robot clamping. The former has high labor intensity and low work efficiency; the latter has complex devices, high equipment costs, and inconvenient maintenance. For example, the nose clip strip welding device provided in the Chinese utility model patent "A cup-shaped mask nose clip automatic welding device" (Announcement No. CN212528742U, announcement date 2021.02.12) provides a nose clip strip welding device, in which the operator puts the nose clip on the ultrasonic welding head, and the worker needs to repeatedly feed the nose clip, which has high labor intensity and low work efficiency.

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-4A mask nose bridge line welding machine comprises a base 1, a mask mold 3 installed on the base 1, and a propulsion cylinder 4. A welding head fixing plate 5 is fixedly connected to the telescopic rod of the propulsion cylinder 4, and a welding head plate 6 is fixedly installed on the welding head fixing plate 5. The front end of the welding head plate 6 is provided with a V-shaped welding groove 61 that matches the shape of the lower edge of the mask mold 3, and the notches at both ends of the V-shaped welding groove 61 are provided with nose bridge line placement grooves 62. A nose bridge line placement frame 7 and a feeding roller 8 that rolls with the top surface of the welding head plate 6 are arranged on the base 1 above the welding head plate 6, a notch 71 corresponding to the feeding roller 8 is arranged on the nose bridge line placement frame 7, and a feeding port 72 connected to the nose bridge line placement groove 62 is arranged at the bottom of the nose bridge line placement frame 7 located at the notch 71, and a tail plate 73 is provided at the tail of the nose bridge line placement frame 7, and a front top plate 74 elastically connected to the tail plate 73 is provided on the nose bridge line placement frame 7. Specifically, the base 1 is provided with a rotating shaft that passes through the unloading roller and is coaxially fixed therewith. The rotating shaft can be connected to a motor (not shown) that drives it to rotate the unloading roller. The bridge of the nose is placed on the bridge of the nose strip placement frame 7. The bridge of the nose is pushed forward by the front top plate 74 so that the bridge of the nose contacts the unloading roller 8. When the welding head plate 6 is pushed forward, the unloading roller 8 rolls. Under the action of friction, the bridge of the nose at the front end falls into the unloading port 72. When the welding head plate 6 is reset, the bridge of the nose falls into the bridge of the nose placement groove 62 from the unloading port 72. The unloading roller 8 is used to realize the automatic loading of the bridge of the nose strip, which eliminates the manual method, reduces the degree of manual labor, and improves work efficiency. In addition, the structure is simple, the equipment cost is low, and maintenance is convenient. In addition, the device can also cooperate with a conveyor belt to fix the mask mold 3 on the conveyor belt to realize the automatic transportation of the mask body, further improve the degree of automation, and thus improve production efficiency.
